Monomer is a great place to stay when you have a trip in Bangkok for several reasons: ideal location (only 2 mins walking to the nearest BTS Rachathewi station), clean & neat room (we spent 3 nights on the dorm room on the 5th fl and really enjoyed it), friendly staff members (front desk-staff spoke really good English and although the other cleaning ladies can't speak English, they supported us a lot) :) Everything is better than our expected. Thanks!
